18.0 - Good Read Indicators
Along with displaying the barcode data and the sled LED flashing green, CortexMobile is programmed to have the phone beep
once when a barcode is successfully read. An app developer can choose a variety of audible feedback indicators as dictated by the
capability of the iPhone. Vibration via the phone can also be an option.
19.0 - CortexMobile Used For Demonstration
To optimize battery life a default time of 1 minute is set for sled inactivity before going to sleep. When you start up CortexMobile
the sleep timer automatically changes from 1 minute to 15 minutes. This allows for convenient demonstration without concern
for the sled going to sleep prematurely. The next time the sled re-boots, the sleep timer setting reverts to the default value of 1
minute.
20.0 - Battery Life Management via the SDK
Power consumption generally depends on scanner and iPhone usage. CortexMobile can demonstrate the SDK’s ability to implement
a sophisticated power management scheme called Intelligent Charging that allows the sled battery to provide power necessary
for scanning and back-up power to a connected iPhone. The sled can do this by monitoring the battery levels of both itself and the
iPhone.
NOTE: Although Intelligent Charging is a default setting on the reader, it can only be implemented if the sled is in iPhone App
Communication Mode and running an SDK-based app. Otherwise the sled will always charge the iPhone until the sled’s battery level
drops to 15% or less.
NOTE: Intelligent Charging can be deactivated by scanning the configuration barcode for one of the other two charge modes
available (Enable iPhone Charging via Sled or Disable iPhone Charging via Sled).
To accomplish Intelligent Charging, CR4405 firmware settings have been created to define key thresholds, which are:
•
“Sled Battery Reserve Level.” This default sled battery threshold is 40%, which means that 40% of the CR4405 battery charge (if
available) will be allocated to scanning for approximately 12 hours, assuming 100 scans per hour.
•
“Sled Battery Critical Level.” This default sled battery threshold is 15%, below which the CR4405 will no longer provide back-up
power to the iPhone, and will reserve power only for scanning and sled management.
•
“iPhone Battery Critical Level.” This default iPhone battery threshold is 25%, below which the CR4405 will primarily charge the
iPhone depending on the sled battery level.
